NeoGAF has dug up another Square Enix trademark, this one for something called Sleeping Dogs, leading some to speculate it’s a subtitle for Kane & Lynch 3 due to the subtitle of the last outing, Dog Days. A job posting from IO Interactive back in September 2011 suggested that a third Kane & Lynch was in the works, and Ian Livingstone himself said in December 2010 the duo weren’t going away any time soon. You can view the trademark filing here, which lists a January 13 date.
